Can you still sign into Snapchat on iOS 12

No. Snapchat requires an iPhone which can run iOS 15 or higher.

The current version of Snapchat requires iOS 15.0 or later.

Snapchat Support – What devices does Snapchat support? says "We support Android devices running Android 5.0 or newer, and iOS devices running iOS 14.0 or higher." I don't know if they actually support iOS 14.*, or just haven't gotten around to making their Support page match their App Store page yet.

Even if you have an old iPhone that is running iOS 12, and an old version of the Snapchat app designed for iOS 12, I would not count on that Snapchat app still working. If it does, it's "Christmas" and is something that could break at any moment.

Note that your tag line says that you have an iPhone 12 mini running iOS 27.

The Snapchat App Store listing for iOS clearly states that Snapchat Version 14.25.0.48 is compatible with iOS 15 and later. This is explicitly mentioned in the App Store information, as shown in the screenshot below.

However, this does not necessarily mean that iOS 15 is the oldest version of iOS on which Snapchat can run. The App Store listing generally reflects the minimum iOS version required for the currently available version of the app.

App developers can, at their discretion, continue to make older versions of their applications available for older versions of iOS. When a user attempts to download an app on a device running an older version of iOS, the App Store may offer the latest version of that app that remains compatible with the particular iOS version on the device.

Therefore, Snapchat may have released different versions over time with different iOS compatibility requirements. A newer version may require iOS 15 or later, while an older Snapchat version may support an earlier iOS release.

The screenshots below support this point by showing that older compatible versions can be made available by the developer from time to time. The availability of such an older version is controlled by the app developer and Apple's App Store distribution system, rather than being determined solely by the compatibility requirement displayed for the current version.

In short, there is an important distinction between:

• The minimum iOS version required by the current Snapchat release, and
• The minimum iOS version supported by an older Snapchat release that may still be available for download.

Thus, seeing “Requires iOS 15.0 or later” for the current Snapchat version does not, by itself, prove that Snapchat never supported earlier versions of iOS. Older versions of the app may have supported earlier iOS versions, subject to the developer continuing to make those versions available through the App Store.

1. As iOS versions advance, some newer apps may not be compatible with older iOS versions. You may need to rely on older versions of apps or find alternative apps that are compatible with your device's iOS version.
2. Ask the App developer to release the app for lower iOS versions also. Netflix & Amazon have done it.

7. If your device is no longer receiving software updates, it may be a good time to consider upgrading to a newer device that is supported by the latest iOS updates. Upgrading to a newer device will ensure that you continue to receive the latest features, security updates, and app compatibility. Selection of a mobile model/brand is driv… - Apple Community
8. Check for App Alternatives: Look for alternative apps that provide similar functionality but are compatible with your current iOS version. There might be other apps available that cater to your needs and are compatible with iOS 15 or lower.
9. Consider Device Upgrade: If your iPhone 7 is not able to run the required iOS version, you might consider upgrading your device to a newer model that supports the latest iOS updates. This would ensure compatibility with the Artists app and other apps that may require newer iOS versions.

Remember to regularly back up your data to avoid losing any important information during the transition to a new device.

It's worth noting that the availability of updates and options may vary depending on the specific device model and its hardware capabilities.
