Apple no longer buy license from ARM

Anyway I'm writing a technical report. You'll all have access to read that report online soon.

On my literature reading on ARM architecture and it's usage of ARM Cotex -A series [used in those mobil
phones and tablets and set top boxes].It told that Apple is no longer buying the Cotex-AX license from ARM.
They have introduces a new processor called Swift. Don't know more information about that newly invented
processor , but it's something not coming from ARM. So the wikipedia page says that it does not used a
licensed core from ARM however things are still unclear.

I need to know what kind of connections are with ARM and Apple still?

however I've gone with lots of readings in this topic.

From those chipworks guys. What those guys do is using a microscope they are reverse-engineering the product.
It's not easy as you think to reverse engineer such.

However the answer is ,
They all sell chips based on ARM processors. That's it. We can't say anything more without getting lawyers involved.
Which I found on stackexchange. Nice answer but not informative enough, however David is my friend. But I need to
know more.

There are already a lots of analysis of A6 apple chip [not cotex-A6]. Such as ,
Information is scarce but the Swift core uses a new tweaked instruction set, ARMv7s, featuring some elements of the ARM Cortex-A15 such as support for the Advanced SIMD v2, and VFPv4.[6] Analysis suggests that the Swift core has a triple-wide frontend and two FPUs, compared to a two-wide core with a single FPU in the Cortex-A9 based predecessor.
^-- from wikipedia.

So anybody could make a processor for their ARMv7 instruction set right. Where ARMv7 is the ISA , instruction set
architecture and processor core somethig like 'Cotex-A9' is belogns to the microarchitecture. Where ARM have
licenses for each processor core. I think what ARM sharing is somekind of a VHDL or Verilog source code to
those companies.

However still unclear, I've recieved -3 points asking that question at SE.

If you have more information please discuss. I'm always like to learn from you.
Specially things like these , such as reverse engineering products like these.

That's all I know and what I found on window shopping and through internet.
