Although we already have the first betas of iOS 26Apple continues to work in the previous version, in this case iOS 18, correcting errors and taking new functions waiting for the next one to be launched, as well as trying to give the last retouch to the devices that cannot have it, this being the last one they will possess.
That is why We have been surprised with iOS 18.6a beta that, except something very rare, will be the last one we will see, focusing, later, yes, in iOS 26, so devices such as the iPhone XS stay in it forever.
What does the beta of iOS 18.6 bring
Normally, the betas of these versions usually last a month, and around the 4 units, so we could see the exit of the public beta of iOS 26 on the same day, or very close, to the final version of iOS 18.6, which does not bring too many changes, but an attempt of stability and performance for the iPhone, which, as we said, will stay here forever.
If you want to try this version, to know your performance first hand, it is very simple, you just have to go to General> software update> Beta updates> select iOS 18.6 Developer Beta.
Do not confuse with iOS 26, which will also appear (if your iPhone is compatible), and which will have many more mistakes, because the first one has just launched, and many people criticize their problems, warming, LAG, etc.
In addition to iOS, Apple, as always, would also have launched its beta for the rest of the systems, so we will also have Ipados 18.6, Macos 15.6, Watchos 11.6, Visionos 2.6 and Tvos 18.6which have different numbers that will end up unifying in the next, with the number 26, as Apple already assured us, so that there is no doubt that we have the last one in all, and we do not have to remember what number each is going.
One of the most important novelties of this version, although I doubt that many of our readers are interested, is that finally Apple Intelligence is available in Chinaso that the inhabitants of this country can already try all the functions of AI, something that in the end affects us all, because there are millions of people who will have access, which should motivate Apple to continue improving this intelligence, which still leaves much to be desired.

Remember that, despite the fact that its installation is not as dangerous as iOS 26, it is still a beta, which could contain errors that made your phone work slower, go out, or do not respond to calls, for example, so it is only advisable to do it on iPhones other than our main device, to avoid these problems.
And you, have you already tried this version? Have you seen something interesting, or only stability and a new update to finally close iOS 18? Leave us a comment if you have noticed something, and if you have already tried it. For our part, we will try to cover the novelties of it, although they will be few, really focusing on the important thing, the future iOS 26.
