Build problem

[MarvinQuevedo]

Hi, I am having problems to build my app using your sdk dependency, Need I to make some changes at the new Xcode versions?

I share with you a summary about my system to help you to identify the problem

System Configuration:
macOS: 26.0.1 (Build 25A362)
Xcode: 26.0.1 (Build 17A400)
Flutter: 3.35.5 (Dart 3.9.2)
CocoaPods: 1.16.2 (installed via Homebrew)
📱 Project Configuration:
iOS Deployment Target: 13.0
TangemSdk Version: 3.9.0 (automatically installed)
tangem_sdk plugin: 0.8.0
Podspec dependency: TangemSdk ~> 3.9.0
❌ Main Error:
🔍 Detailed Problem Analysis:
The TangemSdk_secp256k1 module EXISTS and is correctly defined:
Location: TangemSdk/TangemSdk/TangemSdk/Crypto/secp256k1/
Modulemap: Defines module TangemSdk_secp256k1 [system]
Included headers: secp256k1_ecdh.h, secp256k1_recovery.h, etc.
The problem is specific to Xcode 26.0.1:
The module is marked as [system] in the modulemap
Xcode 26.0.1 cannot properly resolve system modules
Previous Xcode versions worked correctly
Versions tested without success:
TangemSdk 3.7.0
TangemSdk 3.9.0 (automatically installed)

and here is the build logs

Hi!

We no longer support wrappers over the native code (Flutter, Cordova, etc.), so their functionality is not guaranteed. Please use the latest version of TangemSdk. No issues have been observed with Xcode 26.
