Thanks for the post, and welcome to Xcode and iOS development!
To download iOS Simulators for Xcode 26.2, use the Components settings within Xcode. Navigate to Xcode > Settings, from the menu bar, then select the Components tab. The Platform Support section displays the latest available platform and Simulator runtimes. To obtain a previously released Simulator runtime, click the Add button (+) in the lower-left corner, select a platform, and then choose the desired version. Click Download & Install to proceed.
Xcode 26.2 includes SDKs for iOS 26.2, iPadOS 26.2, macOS 26.2, tvOS 26.2, visionOS 26.2, and watchOS 26.2. These SDKs are necessary for developing and testing applications for their respective platforms.
There are other methods to download simulators but if you are in Xcode, will be easier if you just use that tool to download the simulators as they should be downloaded after installation.
I would also recommend to update Xcode to the latest release. More information here: https://developer.apple.com/forums/thread/818209
