Do I need to install Yosemite in order to build a Swift iOS app? - macos

I would like to try building a swift app, but I am afraid to upgrade my Mac to Yosemite Developer Preview. I am not clear if this is a prerequisite.

Just to get the official source in here, the Xcode 6 Beta 1 Release Notes state:
Xcode 6 Beta requires a Mac running OS X version 10.9.3 (or later) or 10.10.
And Xcode 6 comes bundled with Swift.

It's not a prerequisite. You can install the XCode 6 beta which includes swift support as long as you have the newest version of Mavericks (10.9.3)

No. I am using Mavericks (10.9.3), and Xcode6 beta is working well, and built program is also working well.

SDK Version Issue.This app was built with the iOS 14.5 SDK

ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 14.5 SDK. All iOS apps submitted to the App Store must be built with the iOS 15 SDK or later, included in Xcode 13 or later.
My current version is macOs Big Sur version(11.4)
and my xcode version(12.5.1)
You need XCode 13 to use iOS 15 SDK. Simply update your XCode and MacOS (if necessary), then build the app again.
After updating XCode, your iOS SDK will be automatically updated.
Instruction for Older macOS:
Use this patch and upgrade your macOS https://github.com/Ben216k/Patched-Sur
After the upgrade, you can install XCode 13 on your older mac.
Here you can see all the supported mac lists: https://bensova.gitbook.io/big-sur/supported-macs
Below are steps I followed to solve the same issue in the same context:
Upgrade macOs Big Sur -> macOs Monterey v12.4
Update Xcode 12.x -> Xcode 13.x or later
Note: Upgrade could take some minutes. Hence, be patient

Is it possible to run on iOS 9.3.1 from Yosemite?

When I try to run from XCode 6.4 I get "iPad may be running a version of iOS that is not supported by this version of Xcode." It won't let me open the Xcode beta either, saying it needs to be on OS 10.11. I need to install an app right now though. Is there a way to do it from Yosemite?
Apple have recently dropped support for Xcode on Yosemite. The last supported version is 7.2.1. If you want to use Xcode 7.3 which supports iOS 9.3 and above you'll need to use El Capitan which is a free update for Yosemite users.

Can I install XCode 7.3 on OS X 10.10 Yosemite?

I'm unable to upgrade my OS X to 10.11, due to reasons.
XCode 7.3 seems to be the first XCode not to be compatible with Yosemite 10.10.
Has anyone succeeded in getting XCode 7.3 to work on Yosemite?
(What's the important update to XCode that has to make it uncompatible with Yosemite?)
Unfortunately no, you can not.
You need OS X 10.11 or later (El Capitan), since March 21st.
So you either update from Yosemite to El Capitan or stick with your current Xcode.
Important? I will say not that much... iOS 9.3 and Swift 2.2, if you are fond of... With the rest of the OSs. The rest is pretty much the same, it's not a major update.
IF you are here because you updated your device (iPhone, Apple TV etc) and can no longer export your apps to this updated device, there is a workaround!
You can actually copy the newest version of iOS XCode SDK from a newer version of XCode into your older version of XCode.
1
Rename your old XCode.app to XCode7.app, and install the latest version of XCode (yes you can have multiple versions)
2
Grab the folder in your new XCode package content folder:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.3\
And add it in the same place of your XCode 7.3 or 8.2 version
/Applications/Xcode7.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
Restart XCode and you will be able to keep working!

How to run Xcode 4.3 or Xcode 3 in OS X 10.8 (Mountain Lion)

Because iOS7 needs Xcode 5, and Xcode 5 must run under OS X 10.8, if I update the OS from 10.7 to 10.8, this makes the old Xcode 4.3.3 not work.
Because an old project needs support ARMv6 arch, I still need Xcode 4.3.3 to maintain the app.
How can I have both Xcode 4 and Xcode 5?
Can Xcode 4.6/Xcode 5 can support ARMv6 arch?
Looks like Xcode 4.3 is not supported on 10.8. However, 4.4.1 (includes iOS 5.1 SDK) and 4.6.3 (includes iOS 6.1 sdk) are. Go Apple's developer download site and search for which ever newer version of Xcode 4 that works for you.
According to Wikipedia Xcode 4.4.1 was the last to support armv6.

Xcode 3 and iOS 6

A newbie question. I have Xcode 3.2.6 and my ipad is iOS 6.0. It seems this version of Xcode doesn't support the iOS version. What version do I need to upgrade my Xcode to so that I can test apps on devices running iOS 6.
And, my second question do I have to download the .dmg to upgrade Xcode. Currently I am running snow leopard 10.6.8.
For iOS 6 you will need Xcode 4.5 and at least Lion (10.7)
You need OS X Lion 10.7.4 or later to install the latest version of Xcode from the AppStore. Then you will be able to build apps to your device with iOS 6.0.
