dyld: Library not loaded: @rpath/SwiftyJSON.framework/SwiftyJSON

I've been using the simulator to test my app. Today I decided to test it using other devices in the simulator and to my surprise it crashes on startup on some devices, on others it works perfectly

My app builds an runs on :

• iPad Air
• resizable iPad
• iPhone 5S
• iPhone 6
• iPhone 6plus
• resizable iPhone

My App crashes on:

• iPad 2
• iPad Retina
• iPhone 4S
• iPhone 5

The Error I'm Getting is :

dyld: Library not loaded: @rpath/SwiftyJSON.framework/SwiftyJSON

Sometimes I even get more information :

I installed SwiftyJson via Cocoapods. My Podfile contains

platform :ios, '8.0'
use_frameworks!

pod 'SQLite.swift', git: 'http://ift.tt/1Shp2s8'

target 'thinx Mobile' do
    pod 'SwiftyJSON', '~> 2.2.1'
end

I tried :

• clean & rebuild
• solutions 1, 2, 3 from dyld: Library not loaded: @rpath/libswift_stdlib_core.dylib
