Hey there
The drying of fruits means water will be evaporated from it. Therefore it is a physical change. Any change that occurs without altering the chemical composition is called a physical change.

A chemical change is one in which the basic molecular formula of the substance has changed, e.g. H2O (water) changes into hydrogen and oxygen.
Physical change refers to a change of state of the substance but not a change in its chemical formula. The fruit in question has only become dried, it has lost water, but that water is still water just gone some place else, the chemicals in the fruit by and large remain unchanged. I don't think anyone can guarantee with absolute certainty that no chemicals has changed, as fruits do contain complex molecules that may breakdown at times, but in general such breakdowns are not attributable to the act of drying.
Please note that although the textbooks like to state that physical change is reversible, the reversals are not usually what you would expect, here's why... Take for example an ice cube melts to form a puddle of water, and then we freeze the water again, but we dont get an ice cube back but more like a sheet of ice. Yep it's not always easy to get back the original shape even though the changes are physical.
