Adding several pods increases iOS app launch time by 10+ seconds

I'm doing an iOS app project in Swift 1.2, using Cocoapods 0.37.2, Xcode 6.3.2. After adding around 8 pods in my project, app launch time greatly increases (around 10 seconds more) on device (iPhone 5). (Note: launch time means the time when you tap the app icon to open the app)

It is so slow iOS terminates it because it doesn't launch in time. The top of the crash log is as follows...

Application Specific Information: com.tryslowappswift failed to launch in time

Elapsed total CPU time (seconds): 27.720 (user 27.720, system 0.000), 68% CPU 
Elapsed application CPU time (seconds): 0.074, 0% CPU

You can test this by:

Note: I have created an example Swift project with all the pods setup in my github repo. You can just clone and run it on your device and see the delay for yourself.

• Create a new blank project, nothing in the application:didFinishLaunchingWithOptions: method
• Run the app on device and see the app launch very fast.
• Stop. Now try adding a Podfile with about 8 pods (no matter big or small the pods are), do pod install.
• Just for clarity, this is the Podfile I used...

Podfile

source 'http://ift.tt/1czpBWo'
platform :ios, '8.0'
use_frameworks! # required for Swift pods

pod 'Alamofire', '~> 1.2.1'
pod 'NPReachability', '~> 0.2.0'
pod 'ActionSheetPicker-3.0', '~> 1.6.1'
pod 'SDWebImage', '~> 3.7.2'
pod 'KVNProgress', '~> 2.2.1'
pod 'KeychainAccess'
pod 'JazzHands', '~> 0.2.1'
pod 'DGActivityIndicatorView'

• Then run on device again. This time you will notice the 10+ seconds delay, even before application:didFinishLaunchingWithOptions: method is called. No import, no bridging header files, just install the pod into the project and it slows down the launch (-- rage guy meme !!! ---)

I suspect this has to do with Swift 1.2 so I tried on a Objective-C project, but I still experience the same delay. It seems to happen right after a normal pod installation, I have no idea how I can optimize or fix this. :(
