Apple Mach -O Linker command failed

Question

After updating my POD install, Xcode sprouted a new issue:

Answer 1

I am using XCode for compiling ionic 3 app.

cli packages: (/usr/local/lib/node_modules)

    @ionic/cli-utils  : 1.10.1
    ionic (Ionic CLI) : 3.10.1

global packages:

    Cordova CLI : 7.0.1 

local packages:

    @ionic/app-scripts : 2.1.4
    Cordova Platforms  : android 6.2.3 ios 4.5.0
    Ionic Framework    : ionic-angular 3.6.0

System:

    ios-sim : 5.0.8 
    Node    : v8.4.0
    npm     : 5.4.0 
    OS      : OS X Yosemite
    Xcode   : Xcode 7.2 Build version 7C68 

There was not write permission in most of the file of ios, which was main issue.
I just changed the permission of ios file and got issue resolved by using command.

sudo chmod -R 775 platforms/ios/ 

Worked great.
