如何停止IBM MobileFirst Platform Foundation在Xcode控制台打印日志

Hey there, I’ve run into this exact verbose logging issue when working with IBM MobileFirst on iOS projects—let’s get those noisy console outputs turned off for good.

1. Adjust the SDK Logging Level #

The core way to control what gets printed to the Xcode console is by setting the logger level directly via the WLClient instance. This will suppress both request/response details and general platform logs unless they’re critical errors.

Objective-C Implementation

Add this code in your AppDelegate.m inside the didFinishLaunchingWithOptions method:

#import <IBMMobileFirstPlatformFoundation/IBMMobileFirstPlatformFoundation.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Set logger level to only show errors (or use WLLoggerLevelNone to disable all logs)
    [[WLClient sharedInstance] setLoggerLevel:WLLoggerLevelError];
    
    // Rest of your app initialization code...
    return YES;
}

Swift Implementation

For Swift projects, add this to your AppDelegate.swift in didFinishLaunchingWithOptions:

import IBMMobileFirstPlatformFoundation

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Set logger level to error-only, or .none to turn off all logs
    WLClient.sharedInstance().loggerLevel = .error
    
    // Rest of your app setup...
    return true
}

• Use WLLoggerLevelNone instead of .error if you want to completely disable all MobileFirst-related console output.
• This will immediately stop the SDK from printing detailed request/response payloads and most non-critical logs.

2. Check for Debug Macros in Build Settings #

If you still see some leftover logs after adjusting the logger level, double-check your project’s build settings for debug-specific macros:

• Open your Xcode project, go to Build Settings
• Search for Preprocessor Macros
• Look for entries like WL_ENABLE_DEBUG_LOGGING=1—remove this macro or set its value to 0 to disable debug-level logging at compile time.

That should cover both of your concerns: stopping request/response prints and silencing all IBM MobileFirst platform logs in the Xcode console.
