GHUnit sumbols for arm64 missing

Question

I try to run GHUnit on the device and receive the following compile error.

ld: warning: directory not found for option '-L/Users/gtaskos/Documents/Projects/My/SDKs/My iOS SDK/My-iOS/Pods/build/Debug-iphoneos'

Strange is I tried the https://github.com/gh-unit/gh-unit/tree/master/Examples/MyTestable-iOS and it works pretty fine.

Some configuration/setup. I have a workspace with a static library project that uses pods for a dependency, in that project I have a OCUnit tests target, a framework aggregate and added an Empty Application target that configured to use GHUnit, added the framework and used the GHUnitIOSAppDelegate in the main.cs.

Then I added an Objective-C class with a custom name MyMintGHUnitTests.m which has some methods (although only testStrings is available when I run the target, that is another question for StackOverflow).

- (void) testGetDetailsAsync
    {
    // Call prepare to setup the asynchronous action.
    // This helps in cases where the action is synchronous and the
    // action occurs before the wait is actually called.
    [self prepare];

    [self.utility getDetailsNumWithBlock:^(NSNumber *total)
        {
        GHTestLog(@"Details Number: %@", total);
        GHAssertNotNil(totalCrashes, nil);
        [self notify:kGHUnitWaitStatusSuccess forSelector:@selector(getDetailsAsyncTest)];
        }
    failure:^(NSError *error)
        {
        GHTestLog(@"Failed to get details: %@", error.description);
        GHAssertNil(error, nil);
        [self notify:kGHUnitWaitStatusSuccess forSelector:@selector(getDetailsAsyncTest)];
        }];

    // Wait until notify called for timeout (seconds); If notify is not called with kGHUnitWaitStatusSuccess then
    // we will throw an error.
    [self waitForStatus:kGHUnitWaitStatusSuccess timeout:5.0];
    }

Class inherits from GHAsyncTestCase.

Maybe I should say that I also use pods for the GHUnit target.

The target runs on Simulator (without my methods) perfect fails on device.
