AIR 31 and -platformsdk switch of iOS12 Beta - unable to compile

[el111]

Firstly many thanks for AIR 31 Beta. I am glad I am able to run on iOS12 Beta.

Problem Description:

When I use Xcode10 beta to compile with iOS 12 beta SDK I receive compile errors

Steps to Reproduce:

Compile basic Hello World AIR app for iOS 12 beta using Xcode 10 beta 5 and the switch:  -platformsdk /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

Actual Result:

ld: library not found for -lstdc++
ld: library not found for -lstdc++
Compilation failed while executing : ld64

If I copy + replace ld from

/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

to

/AIRSDK_31Beta/lib/aot/bin/ld64/ld64 I receive the following error:

dyld: Library not loaded: @rpath/libtapi.dylib
  Referenced from: /Users/xxxxx/SDKs/AIRSDK_31B/lib/aot/bin/ld64/ld64
  Reason: image not found

I have attempted to copy libtapi.dylib from xctoolchain to several folders under the AIRSDK but I still receive the image not found

Expected Result:

I can use  -platformsdk switch to compile using Xcode 12 beta

Any Workarounds:

None Known

I have added same bug the the issue tracker https://tracker.adobe.com/#/view/AIR-4198714

Awesome, thanks!

Also does that mean that AIR is going to be compiled against IOS 12 SDK?

Hello Everyone,

The beta is now live (Adobe AIR 32 Beta | application development - Adobe Labs ) and we would love to hear feedback from all of you. Thanks for your patience.

Regards,

Rohit

Unfortunately AIR 32 give an invalid input error, most likely because of out of date ANEs. Updating the ANEs leads to a ton of errors to do with those ANEs. It may take some time to fix those errors before being able to see if the platform switch side of things is improved.

Hi Rohit Guglani​

I'm afraid there is very little that is actually working with this Beta.

Hello el111

Have you tried the workaround mentioned for this error in release notes? Kindly let us know if you are able to reproduce the issue after replacing the ld64 file.

Regards,

Rohit

[el111]

Hi Rohit Guglani​

I get the same Swift signature issue using either ld64 included with AIR or swapping out with the one from Xcode

eg rename and them symlink

ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld /Users/SDKs/AIRSDK_32/lib/aot/bin/ld64/ld64

Here is using code sign -vv if I unzip the .ipa and cd to /Frameworks

codesign -vv libswiftCore.dylib
libswiftCore.dylib: invalid Info.plist (plist or signature have been modified)
In architecture: armv7

For historical reference the same thing was observed last year with trying to use swift 4 with AIR beta27.

See post 09/15/2017 19:14:34 GMT

Tracker

[el111]

Another issue being widely reported is missing _OBJC_EHTYPE_$_NSException symbol when including several 3rd party static frameworks.

This occurs when not setting platformSDK and not using Xcode's ld64

Looks like some private symbols from iOS12 SDK have not been carried over to AIR SDK

Hello,

These errors are related to latest changes made by Apple. To fix these error you need to repackage the ANE with latest AIR SDK.

If errors shown are related to libstd++ you would need to recompile the ANE.

Regards,

Rohit

[marchbold]

The error doesn't seem related to the library change from stdc++ to c++, but to a missing object type.

As I mentioned in the starling forum:

Using the AIR 32 beta causes:

Undefined symbols for architecture arm64: "_OBJC_EHTYPE_$_NSException", referenced from: GCC_except_table0 in ... 

Attempting to link against the 12.1 iOS SDK causes (eg from here😞

ld: unexpected token: !tapi-tbd-v3 file '/Users/marchbold/work/sdks/ios/iPhoneOS12.1.sdk/usr/lib/libc++.tbd' for architecture arm64 ld: unexpected token: !tapi-tbd-v3 file '/Users/marchbold/work/sdks/ios/iPhoneOS12.1.sdk/usr/lib/libc++.tbd' for architecture armv7 Compilation failed while executing : ld64 

Updating the linker alone, still causes:

Undefined symbols for architecture arm64: "_OBJC_EHTYPE_$_NSException", referenced from: GCC_except_table0 in ... 

Then updating the linker AND using the 12.1 iOS SDK is successful.

So I suspect the beta has an old linker and missing some of the iOS frameworks.

I started replacing frameworks in the AIR SDK and found if I update the

CoreFoundation.framework

from the iOS 12.1 SDK (in addition to the linker) then the AIR SDK would start to work correctly again.

I believe this is the framework that normally contains NSException so pretty good guess this is the issue?

[Rohit Guglani]

Hello Michael,

Thanks for the additional details it helped us in isolating the root issue. I have copied few stub files here Adobe Creative Cloud

Kindly copy them in the <AIRSDK>/Lib/Aot folder and let us know if this fixes the issue you are facing.

Regards,

Rohit

[marchbold]

That looks good regarding the missing NSException error so nice work there!

However I believe the linker is still out of date. I'm still getting:

ld: unexpected token: !tapi-tbd-v3 file '/Users/marchbold/work/sdks/ios/iPhoneOS12.1.sdk/usr/lib/libc++.tbd' for architecture arm64

ld: unexpected token: !tapi-tbd-v3 file '/Users/marchbold/work/sdks/ios/iPhoneOS12.1.sdk/usr/lib/libc++.tbd' for architecture armv7

Compilation failed while executing : ld64

when attempting to link against the iOS 12.1 SDK, but if I update the linker, (ie. `cp /usr/bin/ld lib/aot/bin/ld64/ld64` or the one from Xcode) it succeeds. 

[Rohit Guglani]

Hello Michael,

Thanks for confirmation on the NSException. Linker would be a known limitation for AIR 32 and we are working on that to be addressed in a later release. Till that time the workaround of replacing the ld from XCode has to be used.

Regards,
Rohit

[marchbold]

Can you explain to us why you can't update the linker? At least for macOS? It's one of our most common support issues.

[Rohit Guglani]

Hello Michael,

We have been aiming to fix it for both platforms in one go. We do understand the urgency of request.

Regards,

Rohit

[Rohit Guglani]

Hello Michael,

We have released a beta build today containing the fix for linker issues.

Regards,

Rohit

[el111]

Hi Rohit,

I notice that you have also fixed Swift dylibs signing https://tracker.adobe.com/#/view/AIR-4198777

It is marked under "known issues" but I see it actually working as expected now.

Many thanks for that!!

There is one outstanding adt iOS signing related bug that perhaps can be looked at.

Several Entitlements are being applied to Dynamic Frameworks when packaged. This causes ERROR ITMS-90075 on upload to the store.

I have found that an empty Entitlements plist should be used.

I have outlined details in this post and the java to patch - it's a quick fix.

[grahamsmith]

Hi Michael,

Is it possible to use the iOS iOS 12 simulators in Animate yet or not ? .. tried the work around - ld64 etc with AIR 32.0.0.83 but still no joy.  When I copy the ld file from Xcode 10.1 its only 18k the adobe ld64 is 2.2mb .. is that right ?.

But stuck without the sims , would be great to get this sorted well before xmas ..

[el111]

Hi Rohit Guglani​

With the release version I am still getting the same signing error on swift 4.2 or 4.2.1 dylibs I reported 3 weeks ago.

AIR is not code signing these properly. Please confirm you are seeing the same.

It means it is not possible to build Swift based ANEs using Xcode10 with iOS12 SDK features - which was the main reason I created this thread in August.

This is a serious problem and can't wait 3 months to be fixed in AIR33.

Edit: I see in IPASigner the prepareToSignFramework method contains code for reading the hashCode of the dylibs and it has variations for Swift 3 and 4. Perhaps Swift 4.2 has a slightly different offsets.

Edit 2: I have been able to patch adt.jar with the following amendments

IPASigner.java

private int SWIFT_4_2 = 1000;
private int CODE_DIR_HEADERS_4_2 = 104;
...
public void prepareToSignFramework(boolean isDylib, File file)
            throws IOException, GeneralSecurityException {
...
if (version < this.SWIFT_4) {
    rar.seek(finalPosition + (this.CODE_DIR_HEADERS + this.m_frameworkIdentifier.getBytes().length + 1));
} else if (version >= this.SWIFT_4_2) {
    rar.seek(finalPosition + (this.CODE_DIR_HEADERS_4_2 + this.m_frameworkIdentifier.getBytes().length +
                        1) + this.TEAM_ID_OFFSET);
} else {
    rar.seek(finalPosition + (this.CODE_DIR_HEADERS + this.m_frameworkIdentifier.getBytes().length + 1) +
                        this.TEAM_ID_OFFSET);
}
…
}

The CODE_DIR_HEADERS have a different length in 4.2 (104 not 68)

https://tracker.adobe.com/#/view/AIR-4198777

On a separate note,

It is still required to replace ld64 from Xcode to be able to use iOS Simulator 12.1

ld64 included with AIR still gives !tapi-tbd-v3 errors as per Michael Archbold's post.

[peter_nicolai_123]

So far this seems to be working, actually we didn't have to repackage all of our ANEs, after copying ld and libclang it seems to work. I guess we might repackage the rest of them to be on the safe side. Now we can move forward with iOS 12 features - Thanks!

[grahamsmith]

I think we all need to look at this post from Michael at Distriqt, looks like he's spotted the problem ? : -

https://forum.starling-framework.org/topic/air-32-ios-12-issues-resolved

[Colin Holgate]

I emailed Michael the day before he posted there, which got him looking into the issues.

Preran​ Mohanaraj​ can you see if you can get the AIR guys to look into the linker issues?

[iosdeveloper]

I build an ipa using AIR SDK 32 and with above changes to linker file. I have also added iPhone SDK 12.1 from path "Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk". When i publish the app in new iPad Pro (11 inch) my  application does not get loaded in fullscreen. In iPad Pro (both 11 inches and new 12.9 inch), we see a rectangular black border around the app, all four sides do not stretch to the edges of the screen.Is there a new default(launch) image for the new iPAD? How do i support fullscreen mode?

[grahamsmith]

Hi ,

So are you are using the iOS simulator with Animate ? and you copied over the smaller "ld" file from Xcode 10.1 .. not working for me .

RE launch images :-

I believe it's necessary to include default images for BOTH portrait and landscape for the iPad Pros.

(iPad Pro 10.5)

Default-Portrait-834w-1112h@2x~ipad  

Default-Landscape-834w-1112h@2x~ipad

(iPad Pro 12)

Default-Portrait-1024w-1366h@2x~ipad 

Default-Landscape-1024w-1366h@2x~ipad

You won't get screen display at the correct resolution unless you use both launch images apparently.

This is good reference for current iOS launch images..
