Well, I'm new in the Xamarin iOS developing and I think I started with the wrong foot.
I have Xcode 5.0 and Xamarin 4.0.14. I'm looking to make my application work on iOS 6 and iOS 7 as my only testing device is an iPhone 3GS.
My problem is right now everything seems to point as I'm developing for iOS 7, all the buttons are borderless and as far as my knowledge goes, that it iOS 7.
So, how can I make my application work on iOS 6 but still be approved by the Apple Store? (I've read that they'll soon stop accepting iOS 6 app).
P.s I've already read Xamarin.iOS Target iOS 6 SDK
but I'm still not quite there. I've started downloading Xcode 4.6.3 just in case.
I experienced the same problem. Uninstall Xcode, Xamarin.iOS and Xamarin Studio and install these versions:
Download and install:
Xcode 4.6.3
- Go to developer.apple.com/xcode/. Log in. Click
View downloads and on the second screen you should see Xcode 4.6.3
Xamarin.iOS 6.4.3.0
- In order to download this version log in to xamarin.com/. Click on your account and then
Install. Under the big green button click on View all versions. Here you can select Xamarin.iOS 6.4.3 version.
- XamarinStudio 4.0.12
- The process is the same as for
Xamarin.iOS. Only select the third column where you can find other version for XamarinStudio.
If you don't have the latest Xcode and Xamarin.iOS you won't be able to debug your applications with iOS 7 on iOS Simulator.
EDIT
As Peter pointed out, Apple will stop accepting apps which are not built with XCode 5 since February 2014.
You could download Xcode 4.6.3 from the Apple developer portal to developer for iOS 6. Or, you could follow the information at Is it possible to install iOS 6 SDK on Xcode 5?
I'd like to point you to my answer to a similar question and add a couple remarks on top.
That said by adjusting your deployment target to version 6.0 you could start developing. The fact that you only have access to an IPhone 3GS has both advantages and disadvantages.
On the plus side you can be pretty sure that your app will be running screaming fast on all recent iOS hardware, if performance is acceptable on such an ancient device as the 3GS.
The major disadvantage of your setup is that youl would have to rely solely on the simulator to ensure iOS7 compatibility. It's a gamble. And you will have to rely on the AppStore reviewers to know the outcome. (Hint: I've been there)
