Regarding Framework Addition Error

[Akhil Arora]

Hi 

I am building a chromium based browser for iOS and I have a custom .framework which needs to be added to my chrome project.

I have added the framework to project and written below code in Build.gn

config("miniApp_config") {

  framework_dirs = [ "//ios/chrome/app" ]

  frameworks = [

    "iOSMiniAppSDK.framework",

  ]

}

group("miniApps") {

  public_configs = [ ":miniApp_config"]

}

I am able to build the project but while running I am getting error :

dyld: Library not loaded: @rpath/iOSMiniAppSDK.framework/iOSMiniAppSDK

  Reason: image not found

Can anyone help resolving this

You need to add a bundle_data target to inform the build system that the framework needs to be copied into the app bundle, and have your app depends on the bundle_data target.

Thanks Sylvain for your reply
I tried the same approach and was able to successfully incorporate the framework.

Hi

After adding framework , my application was successfully running on simulator but while running on real device i was facing an error for signing the application with the embedded frameworks and i am not able to launch app on device.

Any support on creating a signed bundle with .framework file

[Mike Dougherty]

Can you run on device without the added embedded framework?

If not, check the comments on the code signing gn args here. (and pasted below). I would start by setting ios_app_bundle_id_prefix using "gn args {out_dir}"

 

# Explicitly select the identity to use for codesigning. If defined, must

# be set to a non-empty string that will be passed to codesigning. Can be

# left unspecified if ios_code_signing_identity_description is used instead.

ios_code_signing_identity = ""

# Pattern used to select the identity to use for codesigning. If defined,

# must be a substring of the description of exactly one of the identities by

# `security find-identity -v -p codesigning`.

ios_code_signing_identity_description = "Apple Development"

# Prefix for CFBundleIdentifier property of iOS bundles (correspond to the

# "Organization Identifier" in Xcode). Code signing will fail if no mobile

# provisioning for the selected code signing identify support that prefix.

ios_app_bundle_id_prefix = "org.chromium"

Hi Mike,

I am able to run the application without adding the embedded frameworks.

 

Could you please share some info, how did to solve this issue by using create_signed_build. I am trying to use this template but no success so far.

My scenario: Added custom framework from outside, without using DEPS entry. I copied it to the inside Frameworks/ folder in App bundle. It works fine on simulator, but as soon as I try to run on device, I get some error : installation failed. I know that we need to embed and sign it, embed is working fine, but don't how to inject signin part in this flow.

Using below script to solve embed part:

 

config("CustomFrameworks_config") {

 

  framework_dirs = [ "//ios/chrome/app/CustomFrameworks/CustomApps/Device" ]

 

 

 

  frameworks = [

 

    "iOSCustom1.framework",

 

    "iOSCustom2.framework",

 

  ]

 

}

 

bundle_data("CustomFrameworks") {

 

    

 

 

 

  sources = [ "//ios/chrome/app/CustomFrameworks/CustomApps/Device/iOSCustom1.framework",

 

             "//ios/chrome/app/CustomFrameworks/CustomApps/Device/iOSCustom2.framework", ]

 

 

  outputs = [ "{{bundle_resources_dir}}/" +

 

              "Frameworks/{{source_file_part}}" ]

 

             

 

  public_configs = [

 

   ":CustomFrameworks_config",

 

   ]

 

 

 

 

Regards,

Akhil
