Bug? Cannot build simulator release app using an external library

[falbertini]

Hi,
I have a problem compiling an IOS app that has an external proprietary library from another vendor (iHeraLib), that is needed to connect via bluetooth to a device in a car.
Three years ago the app was compiling correctly.
I have not changed the app since then, but now I need to recompile it for some changes on the application.

When trying to compile using hosted builder, it does not compile.
Looking at the log, seems that the library iHeraLib is incompatible with the library IArchiver:

After removing the IArchiver from the project, it compiles, when pressing F5
But when I try to Build simulator release app, to test the app in a simulator, i get a long error in the attached file
Here a snippet of the long error:

/Users/administrator/Documents/UploadedProjects/<user id>/B4iProject.xcodeproj: warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 11.0, but the range of supported deployment target versions is 12.0 to 18.2.99. (in target 'B4iProject' from project 'B4iProject')

(2 failures)

If I try the build release app it compiles correctly.
But I need to test the changes using the simulator release app.
Why it’s ok with compile (F5), release app, and not with build simulation release ?
Is there anything that I can do to solve the issue ?

Many thanks…

In Main module, Change the MinVersion to 12 and try again

#MinVersion: 12

 

[falbertini]

I have set #MinVersion: 12 but still not build the simulator version
Returns a different error, attached you can find the full error

The error is:
error: no type or protocol named 'HeraLibWrapperDelegate'
31 | @interface iHeraLib : NSObject<HeraLibWrapperDelegate>

Where is HeraLibWrapperDelegate declared?

Does it work if you try to run it on a real device?

 

[falbertini]

How can I try it without publish it on apple store ? Is there a way ?

Thanks
Filippo

 

[Erel]

Not sure that I understand. Do you have a real device and an Apple developer account? Simply run the program.

 

[falbertini]

Yes, I have an Apple developer account and also an iphone but not a mac... but to copy ipa on it to do the test I don't need to publish the compiled binary on apple store, waiting for the check from apple for the release and after that download it from apple store ? Sorry but to debug iOS application I always used your simulator in the past... please, can you explain me this other way ?

Start with these two tutorials:

Creating a certificate and provisioning profile

Don't panic! While this process can be a bit annoying it is not too complicated and you can always delete the keys and start from scratch (which is not always the case in Android). Note that you must first register with Apple as an iOS developer (costs $99 per year). The whole process is done...

Installing B4i-Bridge and debugging first app

B4i-Bridge is an application that you install on the device. It has three purposes: 1. Launch the installation process when needed. This step is done with Apple Configurator 2 if using a local builder (https://www.b4x.com/android/forum/threads/installing-apps-with-apple-configurator-2.128397/)...

And start with a new B4XPages project. Once you get it working, add the library.

 

[falbertini]

Using b4i bridge, to connect to a local device, it compile and works well.
But I need to use the simulator version.
Why it works well with the debug version and does not work, when i compile it with simulator release app?

 

[Erel]

The library probably misses the x86 binary.
