I can\'t get rid of this error!

Answer 1

Ok, I had the same problem just today and started googling it, when I came across this thread. I haven't finished reading the question when the answer struck my mind: I declared a class with an empty constructor

class MyClass{
    MyClass();

    void func_one(){
    // code
    }

    void func_two(){
    // code
    }

    ~MyClass(){
        cout << "Deleting object" << endl;
     }
};

Then I thought why not terminating (not sure if I'm correct with word selection here, but who cares) the constructor of my class with curly braces ({}). So I did:

class MyClass{
    MyClass(){}

    void func_one(){
    // code
    }

    void func_two(){
    // code
    }

    ~MyClass(){
        cout << "Deleting object" << endl;
     }
};

The problem eliminated, my code started working perfectly.

I know, the good practice is to investigate the issue and find the real cause, but this worked for me.

Answer 2

I got the same issues while making a build of Ionic 1 project.

I was able to solve the issue after deleting the file CDVLogger.h & CDVLogger.m

Answer 3

I just had to do import Foundation!

I was using Kitura for Swift server side and kept forgetting this!

Answer 4

The other answers didn't work for me so here I share my solution in case it might help somebody else:

My problem was that I was configuring the Podfile of my XCode-Project for the wrong platform. Changing "platform :ios" at the beginning of my Podfile to "platform :macos" worked for me to get rid of the error.

Answer 5

Maybe you installed a pod file and you are still trying to build from the .xcodeproj file instead of .xcworkspace

Answer 6

Did not have this problem when I built and ran on my own device. Only had this problem with simulators. I just simply restarted my computer and ran it. It worked.
