Xcode 7.3.1 update to 8, Swift2 project with cocoapods fall to build

Question

one week ago I ran my project with a few pods well on Xcode 7.3.1. But now I have upgraded to Xcode 8. When I open the project, it asked me to convert the codes to Swift 3 automatically. If I do not convert, it exists 2 errors in some pods swift file. When I finished converting, it becomes 83 errors!! What should I do to run the project well in Xcode 8? I just use following pods:

pod "TextFieldEffects"
pod 'BTNavigationDropdownMenu'
pod 'LTMorphingLabel'
pod 'Material', '~> 1.0'

Use xcode 7.3 with pods old version file. it should be easy for you. — Lokesh Dudhat, Sep 23 '16 at 05:11
@LokeshDudhat I am downloading Xcode 7.3.1 now. But I wonder if there is any solution to run in Xcode 8? — user6702783, Sep 23 '16 at 05:14
@user6702783 Have you tried upgrading to Swift 2.3 instead of Swift 3? — kennytm, Sep 23 '16 at 05:15
@user6702783 if you have to work with swift 3.0, you need to solve many errors. — Lokesh Dudhat, Sep 23 '16 at 05:21
@kennytm It seems that I have not converted to any version. What should I do? — user6702783, Sep 23 '16 at 05:31

Just Do one Thing -

Open Terminal and run this command

pod update

Because currently you are using an old version.

After that if need pod install again

Under the project direction? Do I also need to update the cocoapods? – user6702783 Sep 23 '16 at 05:17
Yes, by the way you can just open terminal and run this command – iDeveloper Sep 23 '16 at 05:20
One of the pod seems not been updated and it exists some errors after I updated, should I convert the file? or convert into swift 2.3? – user6702783 Sep 23 '16 at 05:27

I also ran "pod install", I believe some pods have been updated, but there are four errors all the same: “Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly. – user6702783 Sep 23 '16 at 05:35
tell me your installed pod version – iDeveloper Sep 23 '16 at 05:36
pod --version 1.0.1 – user6702783 Sep 23 '16 at 05:41
