Xcode 10 upgrade: dyld library error on openssl.framework/openssl

Question

We've just upgraded our app to Xcode 10/Swift 4.2. Now it launches, but hits a dyld error on openssl.framework/openssl. Has anybody seen this, and if so, how did you get around it?

I'm using cocoapods and here are a subset of possible culprits:

pod 'Alamofire', '~> 4.7'                                                               
pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'
pod 'Firebase/Core'
pod 'Firebase/Firestore'
pod 'Firebase/Auth'
pod 'Firebase/Performance'
pod 'Fabric', '~> 1.7.11'
pod 'Crashlytics', '~> 3.10.7'
pod 'CodableFirebase'
pod 'IQKeyboardManagerSwift', '~> 5.0'
pod 'SkyFloatingLabelTextField', '~> 3.0'
pod 'MarqueeLabel/Swift'
pod 'FTIndicator', '~> 1.2'
pod 'SQLite.swift', '~> 0.11.5'
pod 'CarbonKit', '~> 2.2'
pod 'ZHChat', '~> 0.2'
pod 'ReachabilitySwift', '~> 4.1'
pod 'FirebaseMessaging', '~> 2.0'
pod 'IQKeyboardManagerSwift', '~> 5.0'
pod 'Alamofire', '~> 4.4'
pod 'SkyFloatingLabelTextField', '~> 3.0'
pod 'MarqueeLabel/Swift'
pod 'FTIndicator', '~> 1.2'
pod 'SWRevealViewController', '~> 2.3'
pod 'SQLite.swift', '~> 0.11.5'
pod 'CarbonKit', '~> 2.2'
pod 'ZHChat', '~> 0.2'
pod 'ReachabilitySwift', '~> 4.1'
pod 'Firebase', '~> 4.0'
pod 'FirebaseMessaging', '~> 2.0'

I should note that (obviously enough, I suppose) everything was working before the Xcode + pods update.

Answer 1

I don't think the issue is with linking the pods listed. I made a new project, imported these pods, and here was the log (you can see several other pods were imported as dependencies):

[ ~/Desktop] cd PodCrasher/
[ ~/Desktop/PodCrasher] pod init
[ ~/Desktop/PodCrasher] vi Podfile 
[ ~/Desktop/PodCrasher] pod install

When I opened the workspace and compiled, I got errors from three pods:

• MarqueeLabel -- changed Swift language version from 4.2 to 4
• IQKeyboardManagerSwift -- changed Swift language version from 4.2 to 4
• SkyFloatingLabelTextField -- changed Swift language version from 4.2 to 4

Once I did this, the project compiled. I verified that it compiles both for device and simulator. Try cleaning out the derived data folder ( ~/Library/Developer/Xcode/DerivedData ) before building.

If not, then the problem is in another pod not listed here.

Answer 2

Just in case anybody has the same problem; for some reason I had to build openssl.framework separately, and include it as an embedded framework . This was absolutely not the case before, so perhaps somebody who knows better can provide an explanation (as a comment, perhaps?).

Anyway, I used the build from here: https://github.com/keeshux/openssl-apple

All went smoothly, and everything's working now. Don't know why the switch from Xcode 9 to 10 triggered it, but presumably a change in a dependency somewhere.

UPDATE: The framework compiled from the above link gives a "Non-PIE Binary" error when uploaded to the App Store. If anybody knows a fix, their advice would be greatly appreciated.

UPDATE 2: By updating all my pods the requirement for a separate openssl framework was removed, so I've now removed openssl-apple and everything's working again.

Answer 3

Try this (credit to: Dhavi.M):

In /ios folder

1. git clone https://github.com/krzyzanowskim/OpenSSL.git
2. List item
3. make
4. file -> swift packages -> add package dependency -> (project name) -> just next until finish
5. build phases -> Link binary with libraries -> add openssl.xcframework

Try to build again, the issue should be no longer there.
